Quoted from ABE_FLIPS:

4 Months is not much. Things take time... you cant learn everything in 4 months.
Just a kind reminder on TMNT, this game is frustrating and hard AF, not so much with Mando.
If you want to get better at certain games, learn when you can dead bounce or drop catch safely.
Learn how often you lose control from a failed live catch and if its worth it. Learn all those little tricks to reduce risk step by step.
Reflect all your drains, and make sure to understand why you drained. Over time you can implement more risky techniques because you get better.
Watch streamers, and compare how they play. If you see them doing stuff you cant understand, its probably because you are not experienced enough.
Here is a causual game on Mando, try to understand what I am doing and compare it to your playstyle. Ask yourself what you can do better.
Good luck, let me know how it went.
